I HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 677,989, dated July 9,1901.

Application filed February 18,1901. Serial No. 47,829. (ll'o model.)

10 for its object to provide improved means for collecting and utilizingthe. heat and products of combustion that ordinarily escape directlyfrom the stove or furnace to the chimney. It is furthermore designed toprovide the device 15 in the nature of a heating-drum, which is arrangedfor convenient connection with a chimney, so as to receive the heat andproducts of combustion'and finally discharge the same into the chimneyafter the heating capacity thereof has been partly or whollyexhausted,and, finally, to arrange for conveniently controlling the device, so asto shut off the heat therefrom whenever desired.

With these and other objects in view the 25 present invention consistsin the combination and arrangement of parts, as will be hereinafter morefully described, shown in theaccompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

3 5 In the drawings, Figure 1 is a central 1ongitudinal sectional viewtaken through the present device applied to a chimney. Fig. 2 is asectional view taken on the line 2 2 of Fig. 1. Fig. 3 is a transversesectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a similar viewon the line4 4 of Fig. 1; Figs. 5, 6, and 7 are detail longitudinalsectional views of modified forms of the heating-drum.

Like characters of reference designate corresponding parts in all of thefiguresof the drawings.

Referring at first more particularly to Figs. 1 to 5, inclusive, it willbe seen that the present device comprises a drum 1, formed by acontinuous pipe-coil, which is provided with an elbow 2, that isdesigned to be fitted into the usual Stovepipe-opening of a chimney 3,

*8'are hinged to the'res'pective side edges of so that the ascendingheat and products of combustion may pass into the heating-drum, andthereby heat the interior of the room .55

within which the drum may be placed.

In order that the heat may pass into the drum and then be conveyed backinto the chimneyin a continuous current, there is provided a partition4, located centrally within the elbow and extending for the entirelength thereof, the front end of the partition being flush with theouter end of the elbow or pipesection 2 and the inner end of thepartition fitting against the inner wall of the drum or coil at theinner end of said pipe-section. By this arrangement a current of heatmay pass inwardly beneath the partition, thence through the coil ordrum, and finally out over the top of the partition, as indicated'by thearrows.

' To control the passage of the heat, there is provided a damper-plate5., slidably mounted upon either side of the partition, butpreferablyupon the upper side thereof, and designed to be pushed forwardly intothe chimney and against the opposite wall thereof, as shown in Fig. 2 ofthe drawings. For the manipulation of this damper there is provided apush-rod 6, connected to the inner end thereof and projected slidablyoutward through an opening in the outer side of the elbow or pipesection2 and'provided with an outer terminal handle 7, whereby the damper maybe conveniently controlled. It. will of course be understood that theplate is of a widthto readily enter the pipe when it is desired to havethechiinney-flue unobstructed. The opposite duplicate foldable dampermembers the body portion 5, so as to be thrown outwardly in oppositedirections into the plane of the body portion and completely close thechimneyeflue in substantially .the plane of the partition or the upperside of the inletinto 95 the heating-drum, whereby thexheat and productsof combustion are compelled to enter the drum and finally escape intothe chimney-flue above the damper and through the dischargepassageformed between thepartition and the upper side of the pipe-section 2.Each wing or foldable damper member is hinged to the body-plate by meansof corresponding bearing eyes or sleeves 9 and 10, formed upon theadjacent edges of the wing and the plate,

there being a pivot-pin 11 (shown in Fig. 3).

passed through the corresponding sleeves.

\Vhen the damper is to be drawn within the inlet-passage of the drum, soas to permit of the heat passing directly upwardly through thechimney-fiue,the damper-wings are folded inwardly in opposite directionsupon the body, as shown in Fig. 3, so as to reduce the width of thedamper to the width of the body-plate. To facilitate the folding of thewings, each of the latter is provided with a rotatable rod 12, locatedwithin the pipe and having a lateral terminal extension or arm 13connected to the adjacent win g, the opposite end of the rod beingprojected outwardly through the outer side of the drum and provided witha suitable handle 14, whereby the rod may be rotated or rocked to openand close the adjacent damper-wing. The intermediate portion of each rodis mounted in a suitable bearing 15 upon the adjacent portion of theinner side of the inlet-pipe.

From the foregoing description it will be apparent that the presentdevice may be fitted in the ordinary Stovepipe-opening of a chimneywithout altering the latter in any manner whatsoever, so as to collectand employ the commonly lost heat and products of combustion to heat aroom by radiation from the drum. Ordinarily the drum is comparativelysmall, so as to take up no more room than an ordinary heating-stove,-and where the Stovepipe-opening is adjacent to the ceiling the drum mayor may not reach to a point adjacent the floor of the room.

It will of course be understood that the size of the drums may vary andthe shape or design thereof may be changed-as, for instance, as shown inFig. 5, the coil or body of the drum may be substantially circularinstead of rectangular, as shown in Fig. 1, while in Fig. 6 a straightor direct inlet-pipe is employed, the principle being the same in all ofthe forms. In Fig. 7 the drum is formed by a straight pipe having theintermediate partition which terminates short of the outer end of thepipe, so as to form a continuous passage for the heat, the outer end ofthe pipe or drum being closed by means of a removable cap or closure 16,through which the damper-rods pass, the closure being removable tofacilitate cleaning the interior of th drum.
